Our present invention has reference to a ratchet nu't wrench and amongthe objects in view is to provide a simple, cheaply constructed wrenchfor this purpose which is ,.c. designed for general use and in whichthed ratchet wheel connected with the socket of the wrench is engaged byone of two ends of a dog, and the pivot for the dog being provided witha swingable'handle to which w is attached a spring,whereby either of theactive ends of the dog bebrought to engage with the ratchet wheel sothat a nut or the rlike received in ther socket' of the wrench or in asocket member attached to u, the wrench may be easilyand quickly screwedhome or unscrewed without necessitating the removal of the wrench fromthe nut or bolt.

lTo the attainment of the foregoing the invention'consists in' theimprovement hereinafter described and definitely claimed.

In the drawings:

'Figure l isa top plan view of a ratchet wrench in accordance with thisinvention.

Figure 2 is a similar view with parts broken away and parts in section.

Figure 3 is a side elevation thereof with parts broken away.

. The lever or handle l of the improvement is provided at one Vof itsends with the usual spaced plates that form the said end of the leverwith a bifurcated head 2. Thev head plates are heldin spaced relation bybolts or like elements 3 and there is received 35 in the head the usualtoothed wheel 4l formed with oppositely extending rounded portions thatpass through rounded openings in the head 2, the rounded portionsterminating in sockets 5 and 6. respectively. The bore of 4G the socket5 is preferably of hexagonalformation whilethe outer end of the crosssectionally rounded member 6 has its open end rounded inwardly toprovide the same with a squared opening 7. Passing through the part 6above the-opening 7 there is a double headed rod 8, and whereby thesocket members maybe turned by` hand-if desired. Of course, removablesockets are designed to have their Shanks received in the bores of thesockets 5 and 6 so that the'wrench may be employed. for different sizednuts on the heads of bolts.

Between the members comprising the head' there is pivotally mounted asubstantially U- shaped dog 9 whose ends are shapedto pro- '55"' videthe same with teeth 10, respectively. The teeth constitute' theactiveends of they dog. Secured to the center of the dog and journaled inbearing openings in the head 2 of the lever there is a cross sectionallyround- 00 ed pivot member 11, one end ofk which projects through oneside ofthe head, and this projecting end is bifurcated7 as at 12. Theref is receivedin the bifurcated portion l2 of the pivot ll one end of anangle arm 18. 7 The 35 pivot-'11ifor the angle arm is preferablyremovable, and securedto the inner face of the outer portion of the armthere is one endof a y helical 'spring l5, the second end of which beingsecured to an earor like element 16 on the handle or lever adjacent tothe juncture of the head therewith.

By swinging the angle arm 13 on its pivot 14 to either side of the headthe spring l5 will turn the pivot and likewise turn the dog 75" 9 tobring either of its active ends or teeth 10 into engagement with thetoothed wheel 4; so that a nut or like device engaged by the wrench maybe turned in either or in both directions without removing the wrenchtherefrom. The slidable rod or handle 8 may be employed for turning thewrench without the necessity of rocking or imparting an oscillatorymovement to the lever l, but obviouslyk the rod 8 cannot be employed forscrewing a nut or bolt fully home but will materially facilitate thestarting of such nut or bolt before the same is screwed entirely home.

It is believed the foregoing description when read in connection withthe accompanying drawings will fully and clearly set forth theadvantages of our improved device to those skilled in the art to whichsuch invention relates so that further detailed description will not berequired. Obviously we do not wish to be restricted to they speciicstructure herein shown and described and, therefore, hold ourselvesentitled to make such changes therefrom as fairly fall within the scopeof what we claim.

Having described the invention, We clzaiin: vl. A lever having abifurcated end providfing a head, a toothed wheel having roundedportions extending1 therefrom and the opposite sides thereof journaledthrough the head and sockets proj ectingfroni said round` ed portions,asubstantially U-shaped dog having its ends foi'nied'with teetharrangedV between the head, a pivot to which the dog is securedjournaled through the head and having one of its ends bifurcated, anangle arm pivotally secured in the said bifurcation and a coiledpressure spring secured to the angle end of the arni and to the lever atits :juncture with the head.
